What is B&H, I can't find anything called that and I'd like to know where to get the beyer gel pads.

EDIT: Yes I am going to buy a pair of t50rp's very soon once some money comes over, the idea being they're supposedly the best band for buck you can buy with modding at my price point of $129

EDIT2: nevermind found them: http://www.bhphotovideo.com/c/product/580542-REG/Beyerdynamic_900780_Gel_Style_Ear_Cushions_for.html


EDIT3: Will these pads need modding to fit on the t50rps or will they just go right on?

They don't need modding, but they are a PITA to install. Took 1.5 hours to get one on and 40 minutes for the second one. They are just a little bit smaller than Fostex' baffles, have small lips and are made out of plactic that's hard to stretch.

 

To install them, you have to pre-stretch them with your hands. Get a hold on the outer seal where lips attach to the earpad base, together with the lips, get same hold a centimeter away and pull apart. Move on to the next centimeter. Two full rounds would pre-stretch them enough. You can use hands, as I did, but I got a blister after that. Better use some flat-nose pliers. Of course, don't put all the effort into them, they're resilient but obviously have their limits, it's not possible to reach them with hands, but with pliers you can.

 

 

Then, putting them on. I didn't find rolling the lips over to be of any help, as pads are smaller than the baffle. Just insert one side of the baffle between the lips and earpad base, then use one hand to hold positioned lips in place, and other to pick a bit of lips and pull it over baffle edge, then move first hand so to hold a new position. Probably, you'll have to use teeth to pull last bit of lips over the baffle. Then, tape them over as they may slip off in a few days. Better to have someone help you un holding the lips and use small flat non-sharp tweezers to grab and pull the lips. It's really innerving.

 

They stretch a little when in place, so putting them on second time would be easier.

 

PS: you can buy T20RP-mk2 from B&H, they're pretty much the same as T50RP, especially form the modder standpoint.

Could you warm them up a bit to help them stretch easier and expand a bit? Use a blow dryer or something not too extreme.

They do stretch better when heated - I used heating radiator - but not so much and they cool down long before you can put them on. Plus it seems that they de-stretch under heat if you have stretched them before that.

So I finally started with my mods; haven't started the creative stuff yet though.

 

Previously I've put a paper square to serve as reflex 'square'. The change was subtle but appreciated.

Friday I put plasticine in the baffle--only on the outer rim and the ones that were fully walled. Very pleased with the changes in sound.

Today I put paxmate (not paxmate plus) into the cups and... sounds odd :S it's like the upper range (of voices) is all muffled. Around 500Hz I think.

 

I didn't put paxmate over all the cup, rather mainly on the two sides (where the depth is different) and a small strip on the baffle side. Maybe I should have tried at least a circular or square layout because now listening to music, I definitely feel something different/wrong on on the front and back. Also vibrating my ears too much lol.

I'm currently suffering from a case of Fostex guilt.  After all the hundreds of dollars of headphones that I've had through my home in the past year, I have to keep pinching myself to prove that I'm not dreaming.  $83.00 + the extra supplies for this sound I'm getting?  

 

Now, let's just hope I don't break out into full tears in the morning when my Hifiman HE-5LEs arrive and the Fostex 'phones trump them on sound and performance.  This hobby can be dangerous.

 

TV has never turned me into a couch potato because I don't watch much of it.  However, these Fostex 'phones are making a serious couch potato out of me.  I just drop onto a cushion with the Sansui vintage receiver on, remote for the Squeezebox in hand and album surf my life away.

Haha, keep us posted :P

 

I really want to try electrostats but truly not in my price point. I'm just gonna fiddle with the Fostex till I am happy. Which I guess I somewhat was until I put Paxmate. I'm assuming this is because

1) my ears are tired

2) uneven arrangement of Paxmate

3) my current build does not work well with stock pads+white felt+ear-side felt intact.

 

Tried blocking the vents from the outside with tape just for testing purpose and I don't hear any audible difference... well no more headphones for me tonight, I think #1 is weighing more and more.

I completely understand you. Between my T50RPs and my Magnums... I'm wondering why anything else in the world was ever considered to be a 'good buy.'

Guys, you can always sell the equipment you don't need. That's what I'm doing)

Don't worry, I just did full paxmate to the cup and still have nasty midrange peaks, no matter what I try.  Previous setup wast felt line with cotton wool, and that had muddy lower mids but crystal clear and smooth upper mids.  Now it is plasteceiene baffle, no felt to either side of driver, stock pads, paxmate to all of cup no cotton and midrange is probably worse lol - maybe it needs to get worse before it gets better.  Meh 6 hours gone - could have rewired my amplifier.  At least when you rewire gear it doesn't sound any worse loltriportsad.gif

 

I think these might need a)some cotton and b)some material to the front/back of driver to get some control back into the midrange.  

 

EDIT:  It's 1am local time here, couldn't resist to try cotton and felt to back of driver.  Might try paxmate, from memory that warmed up the midrange and bass.  Some more cotton might clean up the upper mids, then I will be laughing.

 

EIDT2:  Ahh much better - sound is a little muffled (maybe felt driver backing?) but sound signature is much improved.  Sounds a bit "closed" - guess there are still some reflections/resonances occurring.  Maybe back of gimbal mount?  Might try some treatments to this area as well as driver backing.  But at least this is ok to listen to now.

Would it be possible to throw on some HiFiMAN velour pads on these things? Is it as easy as picking out your preferred pad and glueing it in-place of the old one?

When I get my HE-5LE headphones today, I can compare the size of the pads and see how close they are for fit.  Remember, the velour pads do add comfort, might be a bit less irritating if you have sweaty ears --- yet, they are reported to not seal as well, thus leading to some loss in bass.
 

 

post #6178 of 10878

So you can basically just get any pads that aren't too big/small and glue them to the cans? and wouldn't velour pads also increase soundstage?

What about velour pads, and to counteract the loss in bass you plug up three of the four holes, rather than than recommended 3 and most of the fourth?

You are correct about the velour and the potential to increase the soundstage as that is something as a benefit that I did happen to read about.  As far as how to attach them to the cups, that remains to be seen.  I guess a lot of it might depend on how long you plan on keeping your Fostex headphones assembled - or, do you have future modifications planned?  If one is at the point of no longer applying some modifications, then they could easily use a small, thin layer of silicone sealant to bond the pads to the cups.  To remove them in the future to swap them out, I'm sure a craft knife would be able to capably cut the silicone to release the pads.  Or, one could just simply use rubber cement, which would do a good job of holding them in place,  yet is quite easy to remove if needed.

 

In regards to the bass holes, that's a part of the Fostex modification process that I haven't been able to grasp yet.  I'm not sure how or what kind of benefits people are achieving with the sound by closing some or all of them off.  Going back to my earlier comment on the T40RP headphones, the sound is not as good as the T50RPs even though the same driver is utilized.  The only differences though  is that the 40s have a smaller cup / shell and the bass ports are plugged.  So, one of the two - either the shell size or the ports being plugged is having some effect on the sound quality itself.

 

post #6180 of 10878

Thankyou for the help wje, as a last quick question, is there a mod (to the headphones themselves, not the pads) that you recommend? There's tonnes of them from putting clay in the backs and covering the driver with felt or something? It's a little daunting, is there one that is gaurenteed to give good results whilst not being  very hard?

Thanks again.
